Cervical Cystic Lymphangioma in Young Adults: A Case Report and Literature Review.

Cystic lymphangioma is a rare benign congenital malformation of the lymphatic system. It usually presents in childhood and rarely in young adults. Its management lacks consensus, and its prognosis varies depending on the location. We report a case of cervical cystic lymphangioma in a young adult with chronic left lateral cervical swelling. Examination revealed a high jugulocarotid swelling, non-pulsatile, and transilluminable. Radiographic exploration suggested a cystic lymphangioma. Histopathology confirmed the diagnosis. The patient underwent a sclerotherapy session, followed by surgical excision. Our case illustrates a rare presentation of cervical cystic lymphangioma in a young adult and aims to increase awareness of this rare entity and provide literature insights into its diagnosis and treatment in adult patients.
